The theory of pentaquarks

Abstract

Is there a theory or good experimental evidence? Bj's question: Pentaquark is created by $e^{+}{e}^{-}$. $2q+q\to$ Baryon $;2q+\bar{q}\to$ Triquark$;2q+$Triquark $\to$Pentaquark Does it live long onough to be observable? Basic physics of constituent quarks and flavor antisymmetry. Report of ${\Theta }^{+}$ violating flavor antisymmetry indicates need for two-cluster model.. Ball in Experimental Court - Some experiments see ${\Theta }^{+}$; others don't. Possible production mechanisms present in some experiments, absent in others; e.g. via $N^{\ast }(2.3\mathrm{GeV})\to {\mathrm{\Theta }}^{+}+\bar{\mathrm{K}}$?
